Twenty five years hence, meteorology will be much different and expand far beyond the traditional weather forecast. Personal sensors will monitor weather nearly everywhere. Advanced computing will allow us to forecast at perhaps minute scales and kilometer resolutions, customized for each particular user. Post-mobile devices will enable instantaneous use of the information – even in remote areas of today’s developing nations. Transportation will be safer, businesses will operate more efficiently, events will automatically schedule around anticipated weather, and much more. Operational weather forecasts will be interlaced with new environmental elements that impact economic, health, energy, and security decisions. Many aspects of our daily lives will change forever. Climate change’s possibilities add a critical dimension to community resiliency. Should global weather patterns be altered, forecasting could become more challenging than today. The recent release of the fifth IPCC synthesis report has brought focus to this particular issue. Dr. Kathryn Sullivan, NOAA Administrator, will lead the session with a keynote on her vision for the meteorology enterprise in the year 2040. Following her keynote, the panelists - representing different demographics and perspectives - will then provide their vision, accompanied by a moderated discussion among the panelists.
